Hi Everyone!

I understand that I am being told that I have multiple configurations of the same thing in my /etc/apt/sources.list (sources that apt uses to pull from). My question: should i go through sources.list and delete these?

If I make a mistake, how can I get the default list of trusted sources to basically "start over"?

Thanks!

Solved: I just deleted the duplicate lines in /etc/apt/sources.list
